The antioxidant properties and the foliar phenol composition of 25 Mexican varieties of Phaseolus vulgaris L. (common bean) were evaluated. Phaseolus coccineus was analysed with comparative aims. The high performance liquid chromatography with photodiode array detection analysis revealed 27 phenolics in the leaves of P. vulgaris (13 quercetin-3-O-glycosides, 8 kaempferol-3-O-glycosides, 2 myricetin glycosides and 4 phenolic acids) and 5 in P. coccineus (2 kaempferol-3-O-glycoside, 2 apigenin-7-O-glycoside and 1 luteolin-7-O-glycoside). All extracts showed high levels of phenols and flavonoids (0.964-5.601 mg g⻹ dry tissue, and 0.287-1.418 mg g⻹ dry tissue, respectively) and relevant antioxidant properties, suggesting that the leaves of the varieties of P. vulgaris are a significant source of natural antioxidants. The foliar phenol profiles were species-specific and, besides, the qualitative variation allowed discriminating among varieties of P. vulgaris. These profiles can represent an important varietal authenticity proof.
